Sofia Kenin Splits With Fila, Now Wears Pironetic

While Naomi Osaka and Emma Raducanu earn multi-millions from numerous sponsors and global brand ambassador contracts, American Sofia Kenin hasn’t been nearly as fortunate.

The 2020 Australian Open champion and 2020 Roland Garros finalist has surprisingly concluded her partnership with Fila after three years (she was previously sponsored by Nike). For 2022 Kenin has signed a $150,000 endorsement deal with a Bulgarian retailer called “Pironetic.” It’s not known at this time the duration of the deal with Pironetic.

Currently ranked no. 12 in the world, the 23 year old Kenin still has endorsements deals with Babolat and Motorola.

Why the American has been unable to attract the abundance of different sponsor’s millions like Osaka and Raducanu have garnered is a very puzzling question.

    Pironetic? Wait—isn’t that named after Bulgarian player Tsvetana Pironkova? 🤔

    That origin of Pironetic is unknown by me at this time Sam. Could be Pironkova’s brand though I never heard she was doing it, Giorgi has her own brand though Giomila.

    Pironetic is indeed owned by Tsvetana Pironkova. It’s been going for several years.

    Thanks Dan, good to know. I will change the photo.

    Glad that Dan was able to confirm this. The first five letters, “Piron,” were really the giveaway. 😎
